When other folks configure your 621, do you do it all through g68/861 or do you have to move the rs232 to the 621 to configure it?

After adding the HD621 to the mconfig file, the option to update it shows up on the crumb trail just after the option to update the G68. So I uploaded the new configuration to the 68 and then to the HD621 via serial.

As mentioned, it is supposed to be set up to work with an all Meridian system out of the box.
